Hi all.I know this problem has been addressed a few times previously in connection with the D90 and the D70. I've been experiencing the same problem with my D80. I've tried all the solutions advised on the forum. I even googled the problem & found this link. http://mansurovs.com/how-to-fix-blinking-err-error-on-new-nikon-dslr-cameras. I've cleaned all the contacts. Done a full camera reset. Changed the SD card. Replaced a fully recharged battery. Tried the camera using each one of my lenses and checked the pins in the SD card slot. Turning the camera off for a few seconds, then turning it back on, does relieve the problem temporarily. But I find the 'err' soon appears again. Especially when I use continuos shutter mode. (Essential when shooting wildlife). A mechanic at a place I used to work had a motto in his workshop which read. " IF YOU CAN'T FIX IT, YOU NEED A BIGGER HAMMER'. It hasn't come to that option yet. Although, buying a new camera has certainly been on my mind. Any advice appreciated...Regards Scotty.
Have had this problem on my D80's. If you wiggle the lens back and forth in its mount (there is a slight amount of play in the lens to camera mount), clockwise/counter-clockwise, can you clear the ERR display ? If so, I would suspect the dirty/corroded contact issue. If it comes back quickly, I would suspect you need some type of anti-corrrosion material on the contacts. I can't say what to use, but others on this site have noted the same problem. Using alcohol as a cleaner apparently can increase the problem due to an increase in corrosion of the terminals. When it happens to mine, I just do the above (wiggle) and the problem goes away for quite a while.
The problem is that "err" is a generic message, and it is conclusively known to represent more than one underlying problem, even on a single model. One thing that I am certain that it represents - in the abstract - is a shutter error, usually but not always due to drifting timing. That isn't something you can fix, but fortunately it's probably covered under Nikon warranty as it isn't a usage error. On the other hand, Err also is what happens if you drop the camera and cause the shutter to get out of square, and that is NOT covered by warranty!
In addition there are likely at least ten or twelve other circumstances, some common and some not, that produce the same "diagnostic."
The recurring nature of this problem on your camera does sound like it's going to need a trip to Nikon.

Thanks Brian. Occasionally the mirror seems to lock up when i'm trying to clear the 'err', which has me leaning towards a probable shutter malfunction. Although I have never dropped the camera, I have had it for 3 years. So the warranty period has well and truly expired. Looks like a trip to Nikon for the camera.....Scotty.
